The water pump is energized by the contact between the first conductive piece 441 and the second conductive piece 433, and water is added into the water tank 4 by the water pump, so that the water level in the water tank 4 is maintained.
As a further improvement of the technical scheme, the height of the bottom of the inner wall of the water tank 4 is higher than that of the bottom of the drinking trough 3. The water level in the water tank 4 is higher than the water level in the drinking trough 3, so that the water in the water tank 4 flows into the drinking trough 3 conveniently.
As a further improvement to the above technical solution, a heater and a temperature sensor are further disposed in the water tank 4. Set up the heater in water tank 4, heat the water in 4 water tanks when the weather temperature is lower in spring winter so that the sheep can drink the warm water of suitable temperature, set up temperature sensor in 4 water tanks simultaneously and be used for responding to the temperature in 4 water tanks. Preferably, a controller is arranged to heat the water in the water tank 4 to 20-30 ℃ when the temperature of the water in the water tank 4 is lower than 10 ℃, so that the water in the water tank 4 is kept at 20-30 ℃.
The working principle is as follows: when no sheep drinks water, the pedal 2 returns under the action of the first spring 21, at the moment, the drain valve 321 is opened, the connecting valve 421 is closed, water in the drinking trough 3 is drained, water in the water tank 4 cannot enter the drinking trough 3 in a supplementing manner, the drinking trough 3 is kept empty, and the floating ball 311 falls under the action of gravity because no water exists in the drinking trough 3, so that the other end of the rotating rod 31 moves upwards to leave the water outlet 41, the water outlet 41 is communicated, and the water inlet is closed; when the sheep is close to the trough 3 and needs drinking water, the sheep steps on footboard 2, footboard 2 sinks under the action of gravity of sheep, the first rack 22 of the in-process of footboard 2 removal and the rotation of second rack 23 drive first gear 322 and second gear 422, thereby open connecting valve 421 and close drain valve 321, after connecting valve 421 is opened, water tank 4 and trough 3 intercommunication, the water in water tank 4 flows into trough 3 through connecting tube 42 and supplies the sheep to drink, when the water in trough 3 reaches the settlement height, thereby floater 311 floats to the settlement height and rotates end cap 312 to delivery port 41 and rotates delivery port 41 shutoff and can not continue water with delivery port 41 shutoff. At this time, if the sheep continues to drink water, the stopper 312 is continuously opened to supply water into the drinking water tank 3 after the water level reducing floating ball 311 in the drinking water tank 3 falls down until the sheep leaves the position of the pedal 2 after drinking water is finished, the pedal 2 returns under the elastic force of the first spring 21, the first gear 322 and the second gear 422 are driven to rotate to close the connecting valve 421, and meanwhile, the drain valve 321 is opened to drain the residual water in the drinking water tank 3.
When the water in the water tank 4 is lowered to a set water level, the floating block 43 and the sliding block 432 fall under the action of gravity and the elastic force of the second spring 434, so that the sliding block 432 falls on the sliding block 432, at this time, two ends of the second conductive block 433 on the sliding block 432 are respectively contacted with the two first conductive blocks 441, so that the disconnected cable is connected, the water pump is powered on, water is added into the water tank 4, after the water is added to a certain water level, the buoyancy of the floating block 43 is greater than the weight of the sliding block 432 and the elastic force of the second spring 434, the sliding block 432 is separated from the sliding rod 44, the circuit is disconnected, the water pump stops adding water, and the water level in the water tank 4 is maintained at a certain position in a reciprocating.
Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; while the invention has been described in detail and with reference to the foregoing embodiments, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention, and they should be construed as being included in the following claims and description.
